Electron Attachment To Molecules In Very High Pressure Gases, Ronald Earl Goans Jun 1974

Electron Attachment To Molecules In Very High Pressure Gases, Ronald Earl Goans

Doctoral Dissertations

Introduction: The study of low energy electron attachment to molecules is of fundamental importance in both the physical and biological sciences. These processes are important in the physical sciences because many molecular parameters can be directly or indirectly determined from electron attachment studies. Such parameters include electron affinities of molecules, electron attachment rate constants and cross sections, autoionization lifetimes of transient negative ion species, bond dissociation energies, and shapes of molecular and negative ion potential energy curves. Electron attachment studies are important in biology because of the large number of low energy electrons that are produced when ionizing radiation interacts …


Environmental Study Of A Portion Of The Middle Ordovician In Sequatchie Valley, Eastern Tennessee, Ernest Wilson Blythe Jr. Jun 1974

Environmental Study Of A Portion Of The Middle Ordovician In Sequatchie Valley, Eastern Tennessee, Ernest Wilson Blythe Jr.

Doctoral Dissertations

A detailed depositional environmental analysis of a portion of Middle Ordovician Carters Limestone and Hermitage Formation in Sequatchie Valley in East Tennessee was made using six stratigraphic sections as closely spaced as permitted by reasonably complete outcrops. The approximately 60 feet of rocks of this stratigraphic interval include 18 distinct lithologies as determined from a field study and examination of samples collected at one foot intervals and closer with changes in lithology. Two bentonite beds generally accepted as being isochronous units offer a time framework. In all 565 samples were collected and of these 447 were cut, polished, and an …
